Washer – Flat

Hayn Flat Washers are 18-8 stainless steel standard bearing washers for Traditional Cable Rail termination hardware, available in nine nominal sizes from 3/16" through 1" to suit the full range of Hayn termination stud and hex nut thread sizes.

Strong Where It Matters

Washer - Flat

The flat washer seats between the nut and the post face to distribute clamping load evenly at the termination point and protect the post surface from direct contact with the nut during tensioning. Nine sizes from 3/16" through 1" cover every thread size used across the Hayn Traditional cable rail termination stud, hex nut, and toggle jaw hardware range, making it straightforward to specify the correct washer for any assembly without sourcing from outside the Hayn catalog. For applications where greater load distribution across a larger bearing area is needed, see the Hayn Fender Washer series.

Engineered In America Every Hayn fitting is designed and manufactured at our facility in Rocky Hill, Connecticut — the same American workmanship that has set the standard for stainless steel rigging hardware since 1950.
Cold-Worked Production Hayn fittings are cold-worked, not cast. That distinction matters: the cold-working process refines grain structure, increases fatigue resistance, and produces a fundamentally stronger component — one built to perform when the load comes on it.
Precision Manufacturing Our Rocky Hill production floor runs CNC vertical mills, CNC lathes, large-capacity mill-turn centers, and waterjet cutting systems — all configured to produce hardware that meets exact specifications, every time.
75+ Years of Excellence Hayn has been engineering and manufacturing marine and architectural rigging hardware since 1950. That track record isn't just history, it's the design knowledge, failure data, and continuous improvement that goes into every product we make.
